CHALK-ERASER HOLDER.

Specification of Letters Patent.

Patented Aug. 18, 1908. l

Application led October 8, 1907, Serial No. 396,457. Renewed July 8, 1908. Serial No. 442,620.

To all whom it may concern:

Be it known that 1, FRANCIS O. WOODS, a citizen of the United States, residing at Ogden, in the county of Weber and State of Utah, have invented certain new and useful Improvements in Chalk-Eraser Holders, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in chalk eraser holders, and has for its object the provision of means for facilitating the supporting of the eraser, out of contact with the chalk dust, which accumulates in the chalk receptacle; the chalk receptacle ordinarily being the blackboard ledge, which is provided with a longitudinallyextending trough.

Another object of the invention is the provision of means for facilitating the cleaning of the eraser and the directing of the chalk dust or particles into a suitable receptacle for causing the same to be deposited upon a suitable support. Y

With these and other objects in view, the invention consists of certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

1n the drawings: Figure 1 is a fragmentary, top plan view of a device constructed in accordance with the present invention. Fig. 2 is a transverse sectional view of the structure depicted in Fig. 1, and Fig. 3 is a similar view, except the eraser holder is in a raised or substantially vertical position.

Referring to the drawings by numerals, 1 designates a blackboard ledge, which is provided in its upper face with a longitudinallyextending trough 2. The ledge 1 constitutes a receptacle, as will be hereinafter described. Secured to the top of the ledge 1 and, preferably, near its rear edge, is a bead or molding 3, provided with a front, inclined or beveled face 4. The ledge 1 and the bead 3 are normally secured against a blackboard 5.

Between the trough 2 and the bead 4, there is formed, preferably, a horizontal portion 6, to which is attached the eraser holder.

The eraser holder comprises, preferably, a wire frame 7, which frame 7 is attached, by

L"wardly-projeoting edge of pan 9.

bing the eraser over the wire mesh, said any suitable fastening means, as for instance, eye-bolts 8, to the horizontal portion 6 of the ledge 1. vThe eye-bolts 8 constitute hinges whereby the holder is pivotally connected to the ledge 1, which ledge constitutes a receptacle. To the frame 7, there is secured a pan 9, which pan 9 is provided with an open bottom. As said pan is cut away, at 10, it has its upper edges preferably bent around the front and ends of the wire frame 7, thereby leaving the rear portion of the frame 7 uncovered. The pan 9 is adapted to have a part of its lower portion rest against a portion of the trough 2 of ledge 1, Figs. 1 and 2, whereby said pan constitutes a flanged structure of the ledge 1 for preventing the chalk dust or particles from being spilled or floating over the outer edge of the ledge, consequently, conning the chalk dust to the trough, and causing said chalk dust to eventually settle in the trough. The upper front edge of pan 9 extends a considerable distance above the rear portion of frame 7, Fig. 2, whereby the removal of an eraser, shown by dotted lines 11, Fig. 2, laterally olf of the holder, over its front portion, is normally prevented, as said eraser is retained in an inclined position, upon, preferably, va Wire mesh 12. The wire mesh or fabric 12 is secured to the rear portion of frame 7 and to the inner face 'of pan 9 throughout its entire length the securing of said wire mesh to said frame and pan is, preferably, accomplished by soldering the edges thereof. As the wire mesh is normally in an inclined position, the eraser 11 placed thereon will be tilted, rearwardly, which tends to prevent said eraser from falling over the front of the holder in addition to the up- By ruberaser can be cleaned and the chalk dust or particles will be guided into the trough 2, if they do not fall directly therein.

When cleaning the black-board 5, any chalk dust or particles falling towards the ledge 1 will be guided by the inclined, beveled face 4 of the bead or molding 3 downward, and subsequently, will be deposited into the trough 2 of the ledge.

1 have, preferably, illustrated the chalk holder as pivotally connected to the ledge 1, but it will be obvious that any suitable receptacle may be employed for supporting the chalk holder, and owing to the open bottom of said holder, the chalk will be deposited into the supporting-receptacle; It will, therefore, be noted that the ledge 1 not only constitutes a support for the chalk holder, but also a receptacle for receiving the chalk dust, which is either' removed from 4the blackboard or from the eraser. Furthermore, it will be understood that if the eraser is tossed upon the wire mesh or netting 12, this will tend to clean the eraser, as loose particles of chalk will be removed from the same and dropped into the trough.

When it is desired to clean the receptacle, or trough 2, it will only be necessary to swing the holder to a substantially vertical position, as illustrated in Fig. 3,' and remove the chalk dust or dirt from the receptacle or trough 2. After the trough has been cleaned, the holder can be swung down to its normal position, Fig. 2, and it will then be ready to receive the eraser or erasers, and assist in collecting the dust or chalk, and cleaning the eraser.

The pan 9 is reinforced around its upper edges by means of the wire frame, as said edges of the pan are, preferably, rolled or bent around said frame. The eraser holder is constituted by a frame, which is provided around a portion thereof, with a depending flange or pan that constitutes a movable iiange for the support.

What I claim is:

1. In a device of the character described, the combination with a ledge or support provided with a trough, of a frame hinged at its 'rear portion to said support, a pan provided with an open bottom iixedly secured to the front portion of said frame and constituting a flanged edge for said support, and means for supporting an eraser upon said pan and frame.
